Much has been said about the controversial new hosts of CNN’s Crossfire, but they were barely visible on Thursday evening as Reps. Michele Bachmann (R-MN) and Charlie Rangel (D-NY) took over the show for a knock-down, drag-out fight over Republican attempts to defund Obamacare by threatening a government shutdown over the debt ceiling bill. Things began cordially enough, but soon Bachmann and Rangel were going at each other with little in the way of air between their comments.
